Saw this a couple weeks ago, anyone tried it on our beloved engines?

 

Funny you should bring it up I have been hit a few times over the past few months about it, I'm not a fan of the collector size. Like the TiAL and precision v-band inlets though.

You won't see any improvement in spool or power vs a t4 divided turbine housing, probably be a little worse because of the collector.

 

Yeh, T4 is probably still better, but damn that is sexy!

 

Out of curiosity what size housing is that for? is it set up for a T4 or T6? I see that is says Garrett on the housing.

 

ATP turbo has them

Looks like the divided is available in .61, .83, and 1.01 A/R

 

They are basically a T4 volute though my guess from actually seeing them is they are more a divided T3 than a full blown T4. The collector inlets are oversized at 2" hence why you likely wonder if it's T6.

But with a properly sized collector, would it be that this could create a more compact package?

I'll bet there are people on this board that could make or have made a collector that is matched for a rotary.

 

thats a raw shot

 

The openings are small, but the merge is smooth. It leaves out a skilled fabricator to make a smooth merge. The rear is machined so the pipe fits right in to be welded. I don't know any guys with rotaries running it. Don't quote me on it, but I believe Mike Essa, a pro drifter is using it, and we use it for our shop time attack car. I can't say how much power our car would make with a regular t4 divided flange vs this v band twin entry, but we def don't have a loss of power
